The grey warbler-finch (Certhidea fusca) is a species of bird, one of Darwin's finches in the tanager family Thraupidae. Sometimes classified in the family Emberizidae, more recent studies have shown it to belong in the tanager family.
It is endemic to the Galápagos Islands, Ecuador. This species is closely related to the green warbler-finch, and were formerly considered conspecific, but both species differed in appearance, distribution, habitat, and song. The nominate subspecies is from Pinta and Marchena, becki from Darwin and Wolf, mentalis from Genovesa, bifasciata from Santa Fé, cinerascens from Española, luteola from San Cristóbal, and ridgwayi from Floreana. Grey warbler-finches are found mostly in the shrubland and dry forest of smaller drier islands, and have a suitable coloration for their habitat.
Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist montane forests, and subtropical or tropical dry shrubland.

With luck
About 10% of wildlife watchers report a Grey Warbler-Finch sighting in Galápagos Islands on a given day, based on 1,556 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 114 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June–August and October
In those months about 20% of wildlife watchers report a Grey Warbler-Finch in Galápagos Islands on a given day, against under 5% in January and March, the lowest months. Those are among Galápagos Islands's driest months, with almost no rain against 50 mm in March.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Grey Warbler-Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Galápagos Islands, in our data
Galápagos Islands is the only park on Wallace's Line with enough records to rate Grey Warbler-Finch sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Grey Warbler-Finch is recorded against all the birds logged in Galápagos Islands (1,556 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
